My 90 vanagon has been used only a little this winter, but whether I
park it inside or out, I see at least a little bit of coolant under the
water pump.

It doesn't lose enough to make it run hot, and I keep the coolant
topped up anyway.

I haven't investigated thoroughly enough to determine where it's
leaking from, but I'd like to know if it's time to order a water pump.
Here are the symptoms:

Throughout the winter, slight leak of coolant from waterpump area.

Drove 1000 miles last week to the gulf and back. It was warmer (70s)
down there, and I experience no leak, no drop in coolant.

I've been back for two days and it's been down into the thirties at
night, and I've seen a puddle both days.

Does this sound like a water pump seal?

Thanks,

Jim
